No. I've never been to UT. I was at Penn.

^^ I was at UT but I also had no contact with Prof. Weinberg. I had contacts only with Prof. Robert Herman of physics and civil engineering (a pioneer in Big bang theory, through his work on the cosmic microwave background radiation) who was a co-advisor to me. But not Prof. Weinberg. His passing is a big loss indeed.

Putting it here. This month or the recent past has had some good news.

1. A vaccine for malaria.
2. A vaccine for meningitis.
3. A drug for dengue.

The first two are out and the last one is almost out (on the horizon) along with the drug for COVID by Merck. Now, we have to make these affordable and take it to the people. And beat out the idiots who fear-monger. Maybe we need a Health or Public Health or Medical or Biomedical thread. There a couple of health and medical type threads but those are for India. This is global news.

Talking about self replicating robots which are made from stem cells. So not sure why they are called robots though. I am always wary of artificial creation of organisms.

MRNA vaccine for flu shots do not look promising so far. How many years do you all give before we will be getting mRNA vaccine and DNa vaccine only ?

^^ You mean we will have mRNA vaccines even if they are not very good against regular flu?

I am actually expecting them to improve on this mRNA vaccine for flu shots and expect a time (years or decades) when the primary vaccine type would all be mRNA or DNA.

Considering the short manufacturing cycle , my expectations is that there will be push to convert lot of vaccines to mRNA. Definitely the new vaccines would predominantly fall in this category.

The mRNA vaccines seem to be slowing down Omicron and the Chinese vaccines seem to be rather ineffective against the new mutant. Interesting.

Pig’s heart was transplanted into Man? If this works, days of stent, open heart surgery would be over. The heart was genetically modified to prevent rejection.

Somebody will have a cheetah's heart some day and then we will have a huge furor of whether they should be allowed to race, etc. :-)

It’s surely  a revolutionary step.

But stenting,bypass surgery is a definitive therapy for blocked arteries and Heart transplant's are done for end stage heart disease ,where no option is available.

Let’s hope this therapy of genetically modified pig heart,sustains and will provide treatment for a large population.

Yep, maybe until we can get crispr to flip a DNA or two here and there in our bodies themselves and fix things :-)

Let's hope this works. But, if this does not something else will in the next 10 years or so.

How close are we to make humans live eternally? Or until they want to die? I know we are not that close but are we that far? If you look at the progress that has happened in the last 30-40 years, if you were to live until 100, would it happen by then? Are you sure, there is no chance?
